JANSSON Delete from JSON
by Jeremy McNamara 22 Mar '21

22 Mar '21

Hi Folks - I am using JANSSON to store JSON data in an htable. How does one remove an entire element from a JSON? I do not see a specific function mentioning clear or remove exposed in the Kamailio module, but do see various clear/remove methods in the underlying C library. Below does set the value of key foo to null. I would like to remove both the key and value of foo. jansson_set("null", "$var(foo)", "$var(json)", "$var(result)"); Running Kamailio v5.4 Debian 10 -Jeremy

Kamailio + rtpengine + Freeswitch on public/private network
by Eric Ravelo 20 Mar '21

20 Mar '21

Dear Kamailians, I have Kamailio+rtpengine as a dispatcher in front of FreeSWITCH. Kamailio and FreeSWITCH are on the same private network (in an AWS VPC). Kamailio receives calls on the Public Internet IP address and port, and dispatches to FreeSWITCH on the private network. All calls are coming from a SIP Trunk provider, from the Internet so no NAT on this side. My Hello World scenario is: FreeSWITCH answers the calls, plays a media file and disconnects. Problems: 1) In the INVITE relayed from Kamailio to FreeSWITCH, I can see a Record-Route with the public IP of Kamailio. Hence, the BYE sent by FreeSWITCH is sent to this public IP, rather than going back to the Kamailio path, and the call never gets completed from the caller's point of view. I tried adding record_route() in request_route{} but nothing changes. 2) The SDP part of all the messages coming back and forth from Kamailio and FreeSWITCH all contain the correct private IPs, but still the media file can't be heard on the caller's side. Is RTPengine correctly bridging the RTPs? Kamailio configuration is here: https://gist.github.com/eravelo/b3f026723e27d42354804ef942b34a04 Rtpengine configuration file has: [rtpengine] table = 0 interface = internal/10.20.1.158;external/10.20.1.158!KAMAILIO_PUBLIC_IP listen-ng = 127.0.0.1:2223 timeout = 60 silent-timeout = 3600 tos = 184 port-min = 16384 port-max = 32768 Your help is appreciated. Thank you. Eric R.

received parameter in route URI not used despite path use_received set to 1
by Easy Rider 19 Mar '21

19 Mar '21

Hi I'd like to make sure I've understood correctly how use_received in path module is supposed to work, because I don't get what I expected to get after reading the documentation I've got a little set up with a UAC behind a NAT registering to a kamailio registrar through a kamailio edge proxy (he UAC is a simple sipp script simulating a UAC behind a NAT) path is enabled on both EP and registrar, and use_received is set to 1 on EP the path, contact and via headers in the REGISTER going from the EP to the registrar are : Via: SIP/2.0/UDP 192.168.26.129;branch=z9hG4bK20da.9f4ab6ad25eae6acdd4bd4d655b320ce.0 Via: SIP/2.0/UDP 10.0.0.5:6060 ;received=192.168.26.1;rport=23456;branch=z9hG4bK-105-1-1 Contact: <sip:1000@10.0.0.5:6060>;methods="INVITE, ACK, BYE, CANCEL, OPTIONS" Path: <sip:inside@192.168.26.129;lr;received=sip:192.168.26.1:23456> where 192.168.26.129 is obviously the edge proxy then I place a call to the UAC through registrar the EP receiveds the following INVITE : INVITE sip:1000@10.0.0.5:6060 SIP/2.0 Record-Route: <sip:192.168.26.142;lr> Via: SIP/2.0/UDP 192.168.26.142;branch=z9hG4bKdf25.142eebc72e940d07ad983a858c67f64e.0 Route: <sip:inside@192.168.26.129;lr;received=sip:192.168.26.1:23456> Via: SIP/2.0/UDP 192.168.26.1:34567 ;received=192.168.26.1;rport=34567;branch=z9hG4bK-107-1-1 From: "1001" <sip:1001@my-fake-domain.com>;tag=107-1 To: <sip:1000@my-fake-domain.com;user=phone> CSeq: 1 INVITE Call-ID: 1-107(a)192.168.26.1 Contact: <sip:1001@192.168.26.1:34567> ... The Route header is exactly what is expected, but the edge proxy still sends the request to the request-URI address (10.0.0.5:6060) instead of sending the request to the received address set in the first Route header The path module documentation states : 3.1. use_received (int) If set to 1, the “received” parameter of the first Route URI is evaluated and used as destination-URI if present. kamailio configuration on the EP is almost the default one (just added path support, and modified the REGISTRAR route to forward the request instead on saving the contact, so there is not even a mid registrar on the EP tried with kamailio 5.3.7 and 5.4.4 thanks

Kamailio how to make UAC challenge on Dispatcher failure route
by Antonio Couto 18 Mar '21

18 Mar '21

I have one Kamailio that makes an outbound register on two Asterisk. I have a dispatcher with that same two Asterisk destinations, on INVITE message I call replace_from("", ) in order to call a internal extension and on failure route I receive 401 and call the process of authorization is OK. The problem is that if the first Asterisk fail and I get 500 on failure route I can not call replace_from() because is not valid on the block. Is there any way to make this type of authorization process after receiving a 500 on failure route of dispatcher ? Below my cfg file. Thanks in advance.

Server requirements estimation
by Marat Gareev 17 Mar '21

17 Mar '21

Hello! I'm configuring Kamailio proxy and trying to find instructions or advises for choosing the following options: *Host specific* - Number of cores - RAM size *Kamailio specific* - Number of children to fork for the UDP interfaces - Shared memory size The proxy will not connect to the database, only route INVITEs using the dispatcher. The expected load is 70K requests per hour. Are there any formulas for calculating the parameters?

sip_trace() in branch_route, kamailio 5.1
by Daniel Donoghue 17 Mar '21

17 Mar '21

Hello, Using kamailio 5.1, I am trying to use sip_trace(<internal-sip-uri>) from a branch route to send a copy of the current sip message to another location. Sending the message works fine but I note that the message being sent is the original incoming request and does not contain what was changed for the particular branch. Is there any way to get sip_trace() to send the content of the message for that specific branch? With every blessing, — Daniel Donoghue

dmq support for all transports - udp, tcp, tls, sctp
by Daniel-Constantin Mierla 16 Mar '21

16 Mar '21

Hello, (cross-posting - notification for developers, but also looking for testing support in the users community). So far dmq had support only for UDP, suitable to use for replication over trusted networks (local private network, or vpn). There were couple of discussions in the past about supporting other transport like tcp or tls. Earlier today I pushed several commits to dmq module trying to remove the limitation on UDP, and support the rest of the base protocols available in Kamailio (TCP, TLS and SCTP). Internally, a significant behaviour change is that the first (startup) peer notification is now done in the SIP worker one process, instead of the main process, in order to have all transports initialized. I could not spot any relevant side effect that can happen based on quick analysis, because the code with UDP only support was sending out the KDMQ requests, the corresponding replies could come back later. Anyhow, if any other dmq developer thinks of something not being quite right, reply to the sr-dev mailing list to discuss further. For users community: it would be appreciated if people using dmq can test with other transports (TLS, TCP, ...) and report any problems on sr-users mailing list or open an issue on bug tracker. Interesting test scenarios would be with replication of large amount of data or high rate of replicated requests per second. My testing got to the level of connecting to peers via TLS, trying to ensure the code is no longer limiting to UDP. I will do more, but I thought of giving a notification in early phase and get some feedback in order to avoid advancing too much in a wrong direction.

Dialog using Recod Route, with an asterisk
by Nicki Otte 15 Mar '21

15 Mar '21

Hi everyone I have a question regarding the dialog module. It uses the RecordRoute header, which seems all fine. The situation: I have a setup, where the Kamailio proxy, which is running with the dialog module, is talking to an Asterisk. Now the logic in the Asterisk, is to place a new call, and return in to the Kamailio proxy, which sends it to the PSTN. By the logic of the asterisk, it doesn’t persist with the RecordRoute headers. It starts from scratch with a new callId. Here lies the problem. Because the RecordRoute header isn’t given, then a new “dialog” is made, instead of using the one that is established. Here comes my question. Is it against the standards to make the Asterisk persist with these headers, or am I looking at the wrong solution? If not, I do see the power of the dialog module, when a call bounces between UAS’, but not when an asterisk is in the setup. Another solution could be to use a custom x- header for the dialog id, but it doesn’t look like that is a possibility. Have any of you run into this situation, and might have a solution? Thanks in advance // Nicki Bo Otte

iOS CallKit and tsilo
by Igor Olhovskiy 14 Mar '21

14 Mar '21

Hello! Is there any way to "store" already finished transactions in tsilo? Idea is to deliver, for example, canceled calls to the phone, when call already was answered on other device, but push notification arrive later? Major problem here, that there how it's working on iOS. On iOS phone first show you calling screen, than - app is waking and after app will register and receive invite with tsilo, it updates calling screen with CallerID and other info. But if call was canceled before, calling screen is shown, but app not receiving INVITE, so, call screen is just there for some timeout (for Linphone, for ex, it's 20 sec). Right now I've manage to do it via external SIPP call, that emulates "fake missed call", but maybe there is other way to "store" already dead transactions for some time? PS: Unfortunately, can't solve this on mobile app level. -- Regards, Igor

Trouble with Kamailio/RTPEngine and NAT/Firewall
by PJ Slauta 13 Mar '21

13 Mar '21

Hi, I have a Kamailio/RTPEngine setup with Asterisk on a couple of EC2 instances. There is a public IP and it's setup to accept any ports from our IP addresses. If I DMZ my machine behind my router, I get audio, otherwise I don't get any audio, but the SIP portion of the call connects properly. It isn't specific to my network either, it's the same for my partner on his network. I'm assuming that NAT is getting in the way, although I'm not 100% if it's that or if it's a problem opening ports. I have tried with SIP/RTP Passthrough enabled without success. Can anyone provide some guidance here? Thanks, PJ Slauta

Open separate TCP streams to the same destination
by Sebastian Damm 12 Mar '21

12 Mar '21

Hi, I have a peer that requests separate TCP connections for each registration to their server. Those registrations run through the same Kamailio instance on my side. Now what I tried is to use tcpops and the tcp_set_otcpid function, supplying a previously nonexistant TCP connection ID before relaying the register request. The command itself returns true, however, it does not do anything. The content of $conid of the reply is something totally different. So I guess, this function only works for already existing connections. Is there another way to explicitly tell Kamailio to open up another connection to a peer even though a connection to that peer is already open? Thanks in advance. Regards, Sebastian

Best way to ignore HTTP requests
by Ben Kaufman 11 Mar '21

11 Mar '21

I've set up a server listening on TCP recently, and notice that I'm receiving intermittent, random HTTP requests from the internet. While it would probably be a good idea to enforce a firewall rule to only allow known hosts to communicate, what would be the best way within Kamailio to ignore http requests? Would just checking $rP work? Regards, Ben Kaufman ben.kaufman(a)altigen.com<mailto:ben.kaufman@altigen.com> Director of Cloud Operations AltiGen Communications, Inc.

Kamailio how to make UAC challenge on Dispatcher failure route
by Antonio Couto 10 Mar '21

10 Mar '21

I have one Kamailio that makes an outbound register on two Asterisk. I have a dispatcher with that same two Asterisk destinations, on INVITE message I call replace_from("", ) in order to call a internal extension and on failure route I receive 401 and call the process of authorization is OK. The problem is that if the first Asterisk fail and I get 500 on failure route I can not call replace_from() because is not valid on the block. Is there any way to make this type of authorization process after receiving a 500 on failure route of dispatcher ? Below my cfg file. Thanks in advance.

limits in hashtable
by Fabian Borot 10 Mar '21

10 Mar '21

Hi I have a hashtable with about 2500 elements in it. Some of the key_names are the same and in the config file and I traverse them using the index. The problem that I am having is that not all the values are loaded into memory. Lets say I have 5 entries with key_name and key_values like this: 1.2.34:5060:10.10.10 --> 0001232555690 1.2.34:5060:10.10.10 --> 0004562555691 1.2.34:5060:10.10.10 --> 0007892555692 1.2.34:5060:10.10.10 --> 0003212555693 1.2.34:5060:10.10.10 --> 0006542555694 when I do this kamcmd htable.get mytable 1.2.34:5060:10.10.10[0] kamcmd htable.get mytable 1.2.34:5060:10.10.10[1] kamcmd htable.get mytable 1.2.34:5060:10.10.10[2] kamcmd htable.get mytable 1.2.34:5060:10.10.10[3] kamcmd htable.get mytable 1.2.34:5060:10.10.10[4] I am supposed to get their values on the console but sometimes I can not get the 3rd or 4th value , instead I receive this error error: 500 - Key name doesn't exist in htable. What I have been doing so far is to delete extra/old keys from the physical hashtable and load the values again and then it works for a few days. But there is a process that adds entries to the hashtable and at some point it breaks again and I have to delete again old/unused ones. I can not use 'expire' here because the time it takes to become "old" is unknown/variable. This is how the table is defined..2^16 is more than enough to hold 2500 values. What am I missing here? modparam("htable", "htable", "a=>size=16;autoexpire=0;dbtable=htable;") I have taken pcap captures between the kamailio server and the db and I see all the values being transferred over the network when the kamailio is loading/refreshing the values from the db. Is there another limit somewhere? Also when I try to dump the values I get 'reply too big'. modparam("ctl", "binrpc_max_body_size", 10240) modparam("ctl", "binrpc_struct_max_body_size",10240) ./kamcmd htable.dump a ERROR: reply too big any assistance is highly appreciated fborot

Can't show single location via kamctl
by Jon Bonilla (Manwe) 09 Mar '21

09 Mar '21

Hi all Using version 5.4.x here. I save the registrations with use_domain 0 but I do use the domain module to do some checks. If I execute "kamctl ul" show I can see the registrations but if I execute "kamctl ul show username" I get "ERROR: domain unknown: use usernames with domain or set default domain in SIP_DOMAIN" I understand I should use domain in case I was using it in the usrloc module but I'm not. How can I tell kamctl not to ask for domain? cheers, Jonm -- PekePBX, the multitenant PBX solution https://pekepbx.com

Route - loose_route
by Ilie Soltanici 09 Mar '21

09 Mar '21

Hello, I have a strange issue here with the Route header not been respected by the Kamailio server. I'm getting the INVITE from the SBC-1, adding my own RR header (SBC-2), and send it to the SBC-3 This is the Invite I'm sending outside to the SBC-3 Proxy. ``` INVITE sip:+123456789@192.168.1.1:5060 SIP/2.0 Record-Route: <sip:SBC-2:5067;transport=tls;r2=on;ftag=as2b53df6f;lr> Record-Route: <sip:SBC-1;ftag=as2b53df6f;lr> ``` I'm getting back 200OK with mirrored RR, the call is established successfully. But, the problem is with the BYE message coming from the SBC-3: ``` BYE sip:+123456789@192.168.1.2:5060 SIP/2.0 ROUTE: <sip:SBC-2:5067;transport=tls;r2=on;ftag=as2b53df6f;lr>,<sip:SBC-1;ftag=as2b53df6f;lr> ``` There are 2 routes within a single header. Afaik, loose_function should remove his own Route header (SBC-2) and forward the message to the next Route (SBC-1), or to the URI if there are not other Routes. But, in my case, for some reason Kamailio on SBC-2 is sending the request directly to the URI, bypassing the SBC-1. In the logs I'm getting the following errors: *rr_do_force_send_socket(): no socket found to match second RR (sip:SBC-1)* *rr_do_force_send_socket(): second RR uri is not myself (sip:SBC-1)* To enforce the socket I was trying to use 'sn=interface', then I'm not getting anymore this error - but still, Kamailio sends the message directly to the URI, instead of SBC-1. Is there anything wrong with my config, or I am missing something with the Route headers? Kamailio Version: version: kamailio 5.4.4 (x86_64/linux) bdf4e0 Thank you.

Lookup issue with websockets contacts
by moisesynfante 09 Mar '21

09 Mar '21

I have configured Kamailio for websockets support and I'm having issues whenever I try to lookup a WS registered uac on the location table, it never finds the contact even though the contact is present when I dump the list via kamcmd. This issue only happens with WS, I tested using another user agent with a different protocol and it works fine, not sure if this is related to the fact that WS RURI doesn't really contain the AoR username. The AoR is something like 104-p4f578, but the contact's address stored is something like: sip:f0ck9vph@sjm8i3la4i7n.invalid;transport=ws; -- Sent from: http://sip-router.1086192.n5.nabble.com/Users-f3.html

client TLS session reuse problem
by Rupesh Kumar 09 Mar '21

09 Mar '21

Hi, I am running kamailio 5.2.6 on centos 8 and openssl 1.1.1c and connecting and using it as a proxy sip endpoints to a legacy PBX over TLS. The connection to the backend PBX is over TLS 1.2 . Whenever kamailio initiates a TLS connection to the PBX, it uses session ID and a random session id . The server side has a bug and cannot handle the TLS session resuse apparently because of some bug/issue in caching the TLS sessions. The renegotiation and session_cache is by default turned off and I also explicitly set to 0 via modparam but kamailio would always send the session ID in the initial client hello and this is causing us trouble. Any help would be greatly appreciated. https://kamailio.org/docs/modules/5.2.x/modules/tls.html#tls.p.renegotiation Regards, RK

Kamailio and Asterisk in K8s
by H Yavari 05 Mar '21

05 Mar '21

Hi to all, I am going to run multiple Asterisk instances (Pods) in my Kubernetes cluster. I have a stateless Kamailio sip proxy also. We know that K8s can't handle port range for its services, So we have to use host network for Asterisk deployment. But in this mode, Asterisk pods can't connect to other pods through local IPs and you have to add a second network interface to your pods. One solution is using something like Multus that provides multi-home pods. But it has some issue in host-mode! Also, Using media proxy like RTPEngine in front of Asterisk instances doesn't make a change. You have to run RTPEngine in the host mode or just run it on a VM with multiple NIC.What is the practical solution for this scenario? Thank you. BRHossein

RTPEngine control protocol via TCP
by Alex Balashov 04 Mar '21

04 Mar '21

Hi, Recent versions of RTPEngine (9.x+) implemented support for speaking the "NG" wire protocol over TCP, via the `--listen-tcp-ng` option. Does the Kamailio `rtpengine` module support this, and/or are there any plans to? We've run into a few scenarios where very large responses from RTPEngine can't make it back to Kamailio over the UDP protocol due to fragmentation problems in unique network settings like tunnels. -- Alex -- Alex Balashov | Principal | Evariste Systems LLC Tel: +1-706-510-6800 / +1-800-250-5920 (toll-free) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/

Hunt groups with alias_db_lookup
by Adam McCarthy 02 Mar '21

02 Mar '21

Hello, I'm currently using alias_db_lookup to map inbound calls from my SIP carrier to internal endpoints e.g., 1NXXXXXXXXX(a)sip.example.com -> alice(a)sip.example.com. This works well, but I would now like to simultaneously call alice@ and bob@, e.g. alias_db_lookup(...) # somehow return alice@ and bob@ append_branch("sip:bob@sip.example.com") as described here: http://kamailio.org/docs/modules/devel/modules/tm.html#tm.serial_forking This is effectively a hunt group, where two users are called and once one user picks up the call, the second is sent a CANCEL. How would I acheive this with Kamailio? Thanks, Adam

There is a task to remove a fragment (*a=rtpmap:8 PCMA/8000#015#012*) from the SDP string generated by the rtpengine. *v=0#015#012o=kw 1614043485 1614043486 IN IP4 185.19.237.77#015#012s=kw#015#012c=IN IP4 1.1.1.1#015#012t=0 0#015#012m=audio 31828 RTP/AVP 0 8 101#015#012a=silenceSupp:off - - - -#015#012a=direction:both#015#012a=rtpmap:0 PCMU/8000#015#012a=rtpmap:8 PCMA/8000#015#012a=rtpmap:101 telephone-event/8000#015#012a=fmtp:101 0-16#015#012a=sendrecv#015#012a=rtcp:31829#015#012a=ptime:20#015#012* The most logical option seems to be using the re.subst transformation, but so far no success. $avp(write_sdp_pv) = $(avp(write_sdp_pv){re.subst,/a=rtpmap:8 PCMA\/8000%23015%23012//s}); Сan there be an alternative or am I doing something wrong with the re.subst? -- BR, Denys Pozniak

(changing list to sr-users) Hello, Do you see an iptables rule belonging to the rtpengine module? If you do a test call, are the packet counters increased on this iptables rule? In the log message I see another error related to SRTP, not anything related to the kernel forwarding mode.

UAC changing port for same registration
by Michal Popovic 02 Mar '21

02 Mar '21

Hello everybody, let's have a situation where UAC is behind the NAT and router suddenly change the external port. Kamailio in this case creates two location entries one with old port and one with the new one. Now UAC unregister from the new one and old location remains active until it expires and our support system that is listening to locations changes keep the agent online for other services. Is there any way besides the regular OPTIONS ping from UAS to UAC how to solve this issue? Thanks. Michal

event_route when all modules have been loaded?
by Juha Heinanen 01 Mar '21

01 Mar '21

Is there a way to execute event_route when all modules have been loaded and Kamalio is ready to process requests? I found this in core cookbook, but what if there is no udp sip worker processes? event_route[core:worker-one-init] - executed by core after the first udp sip worker process executed the child_init() for all modules, before starting to process sip traffic -- Juha

unsupported sip invite request-uri format ??
by lgl_hust＠sina.com 01 Mar '21

01 Mar '21

In sip register: Request-URI: sip:ims.mnc001.mcc310.3gppnetwork.org , sip register is ok.In sip invite: Request-URI: tel:310010120073501;phone-context=ims.mnc001.mcc310.3gppnetwork.org, return 478 Unresolvable destination .I saw issue #2287 and #1173 . #2287 deals with register, and #1173 has no result.I want to know how to support such RURI in sip invite, does it need a patch in code ? If so , where and how to modified it . Should i modified kamailio.cfg such as bellows ??? I don't know how modified the kamailio.cfg . if (is_method("INVITE")) {$ru = "sip:ims.mnc008.mcc460.3gppnetwork.org"; # rewrite the "Request-URI"$du= "sip:ims.mnc008.mcc310.3gppnetwork.org"; } Thanks

kamailio debug build

I looked at Makefiles and can see instruction # WARNING: do not add mode=debug or mode=release anymore in the Makefile, # use make mode=debug all instead. By default Kamailio is compiled with # debugging symbols in all cases (-g) and without optimization (-O0). https://github.com/kamailio/kamailio/blob/master/src/Makefile.defs#L749-L751 I do not understand how properly build Kamailio with disabled optimization. Could you let me know how to use "mode=debug"? Sergey

Parse multiple URI
by Duarte Rocha 01 Mar '21

01 Mar '21

Greetings, I have a Kamailio proxy where i'm doing some operations over multiple History-Infos and they come in two forms : Scenario 1 -> History-Info : URI1 History Info : URI2 Scenario 2 -> History-Info : URI1 , URI2. On scenario 1 i iterate between headers using $(hdr(name)[N]). However, i can't seem to find a similar tool to apply on scenario 2. In the case Kamailio doesn't have it, what would be the best way to iterate the URIS? I was thinking of parsing them using the comma ",", is that safe? Best Regards,

Kamailio 5.4.4 extremely slow carrierroute preloading
by sr.maillists＠gmail.com 24 Feb '21

24 Feb '21

Hi Maillist! Does someone have experience with kamailio 5.4.4 and carrierroutes loading? We have about 50'000 carrierroutes, kamailio 4.3.6 loads them in about 10 seconds. Kamailio 5.4.4 needs about 10 minutes (!) to load the routes if I set the parameter modparam("carrierroute", "fetch_rows", 50000); Withous this parameter, v5.4.4 loads only 2000. - Virtual Machine is an ubuntu 20.04 with all current updates - Kamailio is installed from source - The database is postgres on a separate host I tested this with the same database and same VM, I only recompiled kamailio and made neccessary changes in the kamailio.cfg. In 4.3.6 I disabled the modules tls and jsonrpcs and added the module mi_fifo.so instead. Any Idea where to search? Did I miss something in the update-procedure? Regards Stefan

regarding the kamailio.cfg
by Maharana, Kanhu Charana 24 Feb '21

24 Feb '21

Hi, We are getting some issue in the in sip registration. The scenario is like. Device SIP registration successful with kamalio. Device got reboot abruptly. When the device got power and switched on, device sent a sip registration again. This time the registration is failing in the kamalio. Is there any way to handle it, if the registration request received for a device which is already registered, kamalio should release the old context and start a fresh registration. Regards kanhu

Unregister with Multiple Contacts
by Charles Phillips 21 Feb '21

21 Feb '21

Happy Friday! To clean up contacts that have sent requests to unregister (Expires: 0) I am executing the following after a 200 OK response from the upstream server: reg_fetch_contacts("location", "$fu", "un_reg"); xlog("L_INFO", "Removing unregistered contact From: $si To: $tu Ruid: $ulc(un_reg=>ruid)\n"); unregister("location", "$fu", "$ulc(un_reg=>ruid)”); This produces the desired result when there is only one contact per AoR, but when multiple contacts are present, it seems to delete the first ruid (which makes sense as I am only providing the $fu). So, the question, can I select the contact by call-id or some other unique identifier specific to the desired contact that I can grab from the transaction? Reading the reg_fetch_contact and unregister docs, they do not seem to provide for selection beyond uri. - Charles

loose_route() does not find socket by name
by Juha Heinanen 21 Feb '21

21 Feb '21

I'm returning to this thread, since after some more testing, I found that loose_route() does not (at least always) detect that a pair of route headers denotes itself. In config I have defined: listen=tls:192.x.x.x:8005 name "ext_tls" modparam("rr", "sockname_mode", 1) and Route header looks like this: ROUTE: <sip:tenantX.teams.tutpro.com:8005;transport=tls;r2=on;sn=ext_tls;lr;n1;avp=savp;pm=0>,<sip:192.x.x.x:5070;transport=tcp;r2=on;lr;n1;avp=savp;pm=0> Then this code: loose_route(); if ($du != "") { xinfo("Routing in-dialog $rm <$ru> from <$fu> to <$du> based on route uri\n"); } produces to syslog: INFO: Routing in-dialog ACK <...> from <...> to <...> based on route uri -- Juha

Connection between Kamailio and redirect server
by Igor Potjevlesh 18 Feb '21

18 Feb '21

Hello ! I will have to connect my Kamailio proxies to a routing server which will receive INVITE and replies with 302 and a list of a SIP Contact where (gateways, IP, prefixes or whatever we want) the call must be routed to. I'm wondering what would be the best approach to handle with Kamalio those 302 and then proceed with the routing? For the moment, we use to work with carrierroute. But, since the redirect server will take the routing decision, I believe that carrierroute will no be useful anymore. Thank you for your inputs/experience.

Cockroachdb and kamailio 5.4
by Jonathan Hunter 17 Feb '21

17 Feb '21

Hi Guys, Hope all are well? We are looking to implement kamailio with cockroachdb due to the advantages it gives us in terms of postgres management and clustering. I can see from a previous string http://sip-router.1086192.n5.nabble.com/CockroachDB-and-Kamailio-td189233.h… that someone has attempted this and even created their own branch. Has any further work been done on this, and if so has anyone got any advice/tips relating to it? As I am nervous about potentially using a branch and not a general release of kamailio moving forwards. I appreciate you cant support all database types but I would just be interested to hear people’s thoughts on the topic. Many thanks!

pipelimit with a kamailio cluster
by Daniel Donoghue 17 Feb '21

17 Feb '21

Hello, I have 2 stateful kamailio servers that receive incoming requests, load balanced across the 2 servers by our carrier trunk partners (outside of our control). I am looking at putting certain invites from these trunks into pipelimit to rate limit under some conditions but I have some questions: 1. How will pipelimit establish rates when requests can come in to either of my servers? 2. If pipelimit decides it is time to limit the requests, will both servers respect that limit? 3. does pipelimit rely on a db or can it use dmq, redis or other methods for cross-server communication? 4. Is there a maximum number of pipes that can be defined? Hope somebody can help me answer these questions. With every blessing, — Daniel Donoghue

Advice on handling SIP trunk to a Perimeta SBC
by Björn Bylander 16 Feb '21

16 Feb '21

Hi, So I’m tasked with setting up a SIP trunk to a Perimeta SBC (https://www.metaswitch.com/products/perimeta-sbc). Apparently, > Perimeta hides the topology of networks by rewriting or removing topology-sensitive information from SIP messages. By default, your Session Controller will make the following changes to SIP messages. > > The Session Controller generates new dialog identifiers (call-IDs, From tags and To tags) for each side of the call, so that it does not expose information about your core network to your access networks. > The Session Controller strips Record-Route and Route information from the message. > The Session Controller rewrites Contact and Via headers so that the source IP address is replaced with the local address of the outbound adjacency. > The Session Controller replaces the IP addresses in c= lines in SDP with the addresses it has allocated for media forwarding. For more information on this, see Media addresses and gates. My problem is this: When the Perimeta SBC sends its first INVITE (I can't say anything about any succeeding INVITEs yet) it's added a Record-Route header with the "lr" parameter included which, as far as I can see makes Kamailio think it should use loose routing which is all well I think. But when the SBC sends an ACK for the "200 OK" from the Kamailio side it doesn't include any Route headers and I think that makes it hard for Kamailio (at least with the standard script which is basically what I'm using) to know where to relay the ACK, at least it makes the t_check_trans() call in WITHINDLG after 'is_method("ACK")' return false which makes the script ignore the ACK. Any thoughts or suggestions on how to handle this? Thanks in advance, Björn Bylander

Usage of ldap/db2_ldap
by DEV 16 Feb '21

16 Feb '21

Hi! I'm trying to use the ldap / db2_ldap module in kamailio but I'm stuck because the docs seem to either be outdated or me being on the wrong track. >From what I understand, I need a single ldap.conf but there are two example files with different syntax: 1) https://github.com/kamailio/kamailio/blob/master/src/modules/db2_ldap/ldap.… 2) https://github.com/kamailio/kamailio/blob/master/src/modules/ldap/etc/ldap.… I'm already using ldap realtime for asterisk and want to switch kamailio to use the same objects by using this schema: https://github.com/kamailio/kamailio/blob/master/src/modules/db2_ldap/ser.s… When using syntax from (1) I receive this error: ERROR: ldap [ldap_mod.c:198]: mod_init(): no section found in config_file [/etc/kamailio/ldap.cfg] I double-checked my conf and it matches (1). When using (2), I got an error, telling me I left some tables unconfigured (even when mixing both syntax). What is the correct syntax to use ldap as my auth module and replace mysql auth tables? Thank you. Kind regards Kevin

Re: [SR-Users] Advice on handling SIP trunk to a Perimeta SBC

Hi again, I'm using Kamailio 5.3.2 by the way. Björn Bylander writes: > Hi, > > So I’m tasked with setting up a SIP trunk to a Perimeta SBC (https://www.metaswitch.com/products/perimeta-sbc). > > Apparently, > > Perimeta hides the topology of networks by rewriting or removing topology-sensitive information from SIP messages.

But when the SBC sends an ACK for the "200 OK" from the Kamailio side it doesn't include any Route headers and I think that makes it hard for Kamailio (at least with the standard script which is basically what I'm using) to know where to relay the ACK, at least it makes the t_check_trans() call in WITHINDLG after 'is_method("ACK")' return false which makes the script ignore the ACK. > > Any thoughts or suggestions on how to handle this? > > Thanks in advance, > Björn Bylander

basic help, In over my head in getting a webrtc up.
by Daniel Siemens 12 Feb '21

12 Feb '21

I am trying to get a webrtc setup going. Here is what I have I have asterisk server at 10.123.244.18. The webrtc works internally from the freepbx UCP application As well as the Raspberry phone allocation. This server doesn't have any nat on it all devices are on local / reouted networks. I have a Proxy server at 10.123.245.30 address. This server is located in AWS and has an elastic IP. On this server I have ngiinx that will load the raspberry phone up. What configuration do I need in kamailio and rtpengine to get this working. If I forward port 8089 in nginx to the /ws side on my asterisk server I can get a call to bridge but with no audio and the call end at 30 seconds when remote. It works internally fine. Likely beccuae the web browser can get to https://10.123.244.18:8089/ws ports fine. Thanks. ------------------------------------------------------------------ This email is intended solely for the use of the addressee and may contain information that is confidential, proprietary, or both.

loose_route() fails on domain name
by Juha Heinanen 11 Feb '21

11 Feb '21

Using a domain name in R-R header may not be such a good idea: Feb 11 12:12:06 lab /usr/bin/sip-proxy[735]: WARNING: rr [loose.c:799] rr_do_force_send_socket(): no socket found to match second RR (sip:tenantX.teams.tutpro.com:8007;transport=tls;r2=on;pm=0;savp=avp;lr) Or is there some means to tell K, which FQDN maps to which IP address, when there are many such FQDNs? -- Juha

ds_mark_dst( ) in DISPATCHER
by alirsm 11 Feb '21

11 Feb '21

Hi, In my failover setting using Dispatcher module, I mark the GW if fails to response. OPTIONS are being sent every 30 sec: failure_route[DISPATCH_FAILOVER]{ if (t_is_canceled()) exit; if (t_check_status("500") or (t_branch_timeout() and !t_branch_replied())) { ds_mark_dst("ip"); if (ds_next_dst()) { t_set_fr(0,1000); t_on_failure("DISPATCH_FAILOVER"); route(RELAY); exit; } } } However, Kamailio still recognize it as active gw ( A.A.A.A is down, no response from OPTIONS being sent) $ sudo sercmd dispatcher.list { SET_NO: 1 SET: { SET_ID: 1 DEST: { URI: sip:A.A.A.A:5060 FLAGS: AP PRIORITY: 0 ATTRS: } DEST: { URI: sip:B.B.B.B:5060 FLAGS: AP PRIORITY: 0 ATTRS: } } } Any help would be appreciated.

R-R to MS Teams Proxy
by Juha Heinanen 11 Feb '21

11 Feb '21

When request is sent from Kamailio to MS Teams SIP Proxy, the top R-R URI needs to contain FQDN of Kamailio SIP proxy instead of its IP address. Document https://skalatan.de/de/blog/kamailio-sbc-teams suggest to replace record_route(); call with record_route_preset("SBC-DNS-DOMAIN:5061;transport=tls", "SBC-IP-ADDR:5060"); That works only in a very simple case where the request came in over UDP or TCP and SIP Proxy has only one listening address, i.e., SBC-IP-ADDR. One way to solve the problem might be a new r_r function that would take FQDN of the top R-R URI as argument or introduction of a pv from where the current record_route() function would take the FQDN if it has been set. Any comments or other solutions? -- Juha

No ACK from MS Teams
by Phillman25 Kyriacou 11 Feb '21

11 Feb '21

Dear List Hope this email finds you all well. I have followed the below tutorial on how to integrate Kamailio with MS Teams https://skalatan.de/en/blog/kamailio-sbc-teams However i have been facing an issue with MS Teams with direct routing where MS Teams does not send back an ACK after a 200 OK. The current inbound call flow is the following: *MS Teams ==> Kamailio==>Asterisk* Once Asterisk answers with 200 OK we send this 200 OK back to MS Teams however, MS Teams just doesn't answer back with ACK and call drops. The below trace shows the INVITE coming from MS Teams and the 200 OK we send back. |||||||||||||||||||| ==================== tag: rcv pid: 26135 process: 23 time: 1613025911.983278 date: Thu Feb 11 08:45:11 2021 proto: tls ipv4 srcip: 52.114.132.46 srcport: 4352 dstip: SBC_IP_ADDR dstport: 5061 ~~~~~~~~~~~~~~~~~~~~ INVITE sip:+357XXXXXXXX@SBC-FQDN:5061;user=phone;transport=tls SIP/2.0 FROM: Phillip Kyriacou<sip:+357XXXXXXXX@sip.pstnhub.microsoft.com:5061 ;user=phone>;tag=c3da9477e05d45fca31c24a155af3318 TO: <sip:+357XXXXXXXX@SBC-FQDN:5061;user=phone> CSEQ: 1 INVITE CALL-ID: 9cb9a2f3144e594c87bccda76791c28e MAX-FORWARDS: 70 VIA: SIP/2.0/TLS 52.114.132.46:5061;branch=z9hG4bK0cf2c45 RECORD-ROUTE: <sip:sip-du-a-us.pstnhub.microsoft.com:5061;transport=tls;lr> CONTACT: <sip:api-du-b-euwe.pstnhub.microsoft.com:443 ;x-i=6e5254d9-79c2-4657-b54b-68791aa8e81f;x-c=9cb9a2f3144e594c87bccda76791c28e/d/10/e21a 6ff7125e4cbd91e75ec687fd4c5d> CONTENT-LENGTH: 1097 MIN-SE: 300 SUPPORTED: timer USER-AGENT: Microsoft.PSTNHub.SIPProxy v.2021.2.9.1 i.USEA.7 CONTENT-TYPE: application/sdp ALLOW: INVITE,ACK,OPTIONS,CANCEL,BYE,NOTIFY SESSION-EXPIRES: 3600 v=0 o=- 170239 0 IN IP4 127.0.0.1 s=session c=IN IP4 52.113.40.94 b=CT:10000000 t=0 0 m=audio 51414 RTP/SAVP 104 9 103 111 18 0 8 97 101 13 118 c=IN IP4 52.113.40.94 a=rtcp:51415 a=ice-ufrag:BwFs a=ice-pwd:sFyvnfQ9iH101E80ZKjCxi9+ a=rtcp-mux a=candidate:1 1 UDP 2130706431 52.113.40.94 51414 typ srflx raddr 10.0.137.19 rport 51414 a=candidate:1 2 UDP 2130705918 52.113.40.94 51415 typ srflx raddr 10.0.137.19 rport 51415 a=candidate:2 1 tcp-act 2121006078 52.113.40.94 49152 typ srflx raddr 10.0.137.19 rport 49152 a=candidate:2 2 tcp-act 2121006078 52.113.40.94 49152 typ srflx raddr 10.0.137.19 rport 49152 a=label:main-audio a=mid:1 a=crypto:1 AES_CM_128_HMAC_SHA1_80 inline:Igc2LVM9FH5kQtkRpHw99H5SB7Rd7eKzJy4gdWJg|2^31 a=sendrecv a=rtpmap:104 SILK/16000 a=rtpmap:9 G722/8000 a=rtpmap:103 SILK/8000 a=rtpmap:111 SIREN/16000 a=fmtp:111 bitrate=16000 a=rtpmap:18 G729/8000 a=fmtp:18 annexb=no a=rtpmap:0 PCMU/8000 a=rtpmap:8 PCMA/8000 a=rtpmap:97 RED/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16 a=rtpmap:13 CN/8000 a=rtpmap:118 CN/16000 a=ptime:20 |||||||||||||||||||| ==================== tag: snd pid: 26086 process: 6 time: 1613025917.726664 date: Thu Feb 11 08:45:17 2021 proto: tls ipv4 srcip: SBC_IP_ADDR srcport: 5061 dstip: 52.114.132.46 dstport: 5061 ~~~~~~~~~~~~~~~~~~~~ SIP/2.0 200 OK Via: SIP/2.0/TLS 52.114.132.46:5061;branch=z9hG4bK0cf2c45 Record-Route: <sip:SBC-IP-ADDR:5060;ftag=c3da9477e05d45fca31c24a155af3318;lr=on> Record-Route: <sip:SBC-FQDN:5061;transport=tls;ftag=c3da9477e05d45fca31c24a155af3318;lr=on> Record-Route: <sip:sip-du-a-us.pstnhub.microsoft.com:5061;transport=tls;lr> From: Phillip Kyriacou<sip:+357XXXXXXX@sip.pstnhub.microsoft.com:5061 ;user=phone>;tag=c3da9477e05d45fca31c24a155af3318 To: <sip:+357XXXXXXXX@SBC-FQDN:5061;user=phone>;tag=as659924a4 Call-ID: 9cb9a2f3144e594c87bccda76791c28e CSeq: 1 INVITE Server: MediaGW V1.0 Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY, INFO, PUBLISH, MESSAGE Supported: replaces, timer Session-Expires: 1800;refresher=uas Contact: <sip:357XXXXXXXX@ASTERISK_PUBLIC_IP:5060> Content-Type: application/sdp Require: timer Content-Length: 339 v=0 o=root 411266324 411266324 IN IP4 ASTERISK_PUBLIC_IP s=ASTERISK c=IN IP4 ASTERISK_PUBLIC_IP t=0 0 m=audio 14416 RTP/SAVP 0 8 101 a=crypto:1 AES_CM_128_HMAC_SHA1_80 inline:9PcaAGjbemJKTERlFTcVwmLRQoDSEQPxX0L1a6RF a=rtpmap:0 PCMU/8000 a=rtpmap:8 PCMA/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16 a=maxptime:150 a=sendrecv |||||||||||||||||||| Am I doing anything wrong here that MS Teams wont respond to my 200 OK?

Health Check on Dispatcher Failover
by alirsm 10 Feb '21

10 Feb '21

Hi I have setup failover on Kamailio 5.1 using Dispatcher module as below. On a round robin algorithm, INVITEs are being sent to BOTH healthy and faulty GW. When an INVITE is being sent to the faulty GW, a re-transmission will be sent after "t_set_fr" time to the healthy GW and calls are completed successfully. I was wondering if I can setup the health check correctly so the faulty IP GW can be out of round robin till the health check pass it again, i.e. no INVITE is being sent to the faulty GW as long as the health check not pass it. Your help is greatly appreciated, AL # dispatcher.list 1 sip:X.X.X.X:5060 0 0 1 sip:Y.Y.Y.Y:5060 0 0 # ----- dispatcher params ----- modparam("dispatcher", "list_file", "/usr/local/etc/kamailio/dispatcher.list") modparam("dispatcher", "flags", 2) modparam("dispatcher", "ds_ping_interval", 10) modparam("dispatcher", "dst_avp", "$avp(AVP_DST)") modparam("dispatcher", "grp_avp", "$avp(AVP_GRP)") modparam("dispatcher", "cnt_avp", "$avp(AVP_CNT)") modparam("dispatcher", "ds_probing_mode", 1) modparam("dispatcher", "ds_ping_reply_codes", "class=2;class=3;class=4") modparam("dispatcher", "ds_ping_interval", 5) modparam("dispatcher", "ds_probing_threshold", 1) # Dispatch requests route[DISPATCH] { if(!ds_select_dst("1", "4")) { send_reply("503", "No destination"); exit; } t_on_failure("DISPATCH_FAILOVER"); t_set_fr(0,1000); route(RELAY); exit; } # Failure Route failure_route[DISPATCH_FAILOVER]{ if (t_is_canceled()) exit; if(!ds_next_dst()) { send_reply("503", "Out of gateways"); exit; } t_on_failure("DISPATCH_FAILOVER"); t_relay(); }

http_async_client expected result in $http_rr
by Anthony Joseph Messina 10 Feb '21

10 Feb '21

https://www.kamailio.org/docs/modules/stable/modules/http_async_client says $http_rr will be the HTTP reason phrase. I'm understanding this to mean: Code: Reason: 200 OK 404 Not Found In my current 5.4 build, $http_rr returns empty (not <null> or anything else) regardless of what the server sends in the headers. Am I misunderstanding this? I'm writing an API and was hoping to do send_reply("$http_rs", "$http_rr"); -- Anthony - https://messinet.com F9B6 560E 68EA 037D 8C3D D1C9 FF31 3BDB D9D8 99B6

authenticated INVITE badly managed when topos is activated
by frédéric Gaisnon 10 Feb '21

10 Feb '21

Hi, Here is some more information about my problem. I think that topos impacts challenge computing. Do you have the same behaviour I observed? Do you need more information? My tests were done with kamailio 5.4.3 on Centos7 Without topos activated (note that with topoh activated I have the same good behaviour): CPE - INVITE -> SBC CPE <- 407 ---- SBC CPE - INVITE ->SBC (with proxy-authorization header) -- INVITE --> PROXY (So in this case challenge is validated and INVITE is forwarded) With topos activated: CPE - INVITE -> SBC CPE <- 407 ---- SBC CPE - INVITE ->SBC (with proxy-authorization header) CPE <-407 -----SBC topos configuration: loadmodule "ndb_redis.so" loadmodule "topos.so" loadmodule "topos_redis.so" # ----- topos params ----- modparam("topos", "storage", "redis") modparam("topos", "dialog_expire", 15000) Code used: # IP authorization and user authentication route[AUTH] { xlog("L_DBG", "route[AUTH]\n"); #!ifdef WITH_IPAUTH if((!is_method("REGISTER")) && allow_source_address()) { # source IP allowed return; } #!endif #!ifdef WITH_AUTH if ((is_method("REGISTER")) || ($avp(need_auth) == "1")) { ####need_auth is equal to 1

CANCEL transaction
by David Villasmil 10 Feb '21

10 Feb '21

Hello, When receiving a reply, there's a logic which if true, i must cancel the outgoing invite (can 480 the origination). I tried using something like t_set_fr(10,10); to have kamailio cancel it immediately, but it's not happening. Is there a way to cancel an INVITE/transaction?

Kamailio as MS-Teams SBC
by Davide Zanichelli 09 Feb '21

09 Feb '21

Hello everybody! i am trying a setup of kamailio like sbc for ms teams, I currently have the following scenario: TLS Connection OK Out Call ok (except BYE 481 on reply) my problem is in incoming calls microsoft only supports srtp and my pbx (freeswitch based) only works with rtp, now i was reading that you need to use rtpengine to manage srtp to rtp, unfortunately it seems that rtpengine has become very difficult to build especially with recent os, I was wondering if it is possible to have an alternative to rtpengine for managing the srtp (rtpproxy does not seem to work) has anyone managed to get a working setup? in case it is possible to send a configuration template? Thanks You !!! Davide

Timeout for provisional response other that 100
by David Villasmil 09 Feb '21

09 Feb '21

Hello all, I’m trying to figure out if I can set. Timeout for specific provisional responses. I know I can set timeouts for INV, and restart the timer every time a provisional response is received. But this not what I actually need. What I need is to set a timeout from the 100 Trying to the next 180/183 (or a final response) and set back a 480 if not received. I’m not sure TM would allow me to do that, so maybe using a hash table to store transactions and calculate the time since the INV to the received 180/183. But there’s gotta be a simpler way. Many thanks! David -- Regards, David Villasmil email: david.villasmil.work(a)gmail.com phone: +34669448337

Best SIP reply for service activation
by Duarte Rocha 09 Feb '21

09 Feb '21

Hello, I'm currently developing a service on Kamailio where it's possible to configure redirections for a subscriber using a code. In order to implement that client should send an INVITE with a specific code on the Request URI and the redirection is configured. What should be the best way to answer this INVITE? A 200 OK will make the call answered and doesn't seem the best way. A negative reply (4/5/6xx) would work, but it seems strange to have the operation concluded with success and answering with a negative reply. I found "199 - Early Dialog Terminated" to be suitable, but the documentation suggests it should be used upstream. Thanks in advance for any suggestion. Cheers

Kamailio inbound proxy -> Asterisk
by Mihai 09 Feb '21

09 Feb '21

Hi! Don't know if this is a Kamailio Question, maybe someone had deal with it in the past. I use Kamailio with dispatcher to send the request (registration, invites, all) to my asterisk (inbound) and then the asterisk has the outbound trunks, everything works, but this is little thing in asterisk when entering the "sip show peers" it shows me that all the peers are registered with the kamailio IP, if I set the nat option to no, it will show me the correct IP but breaks other clients. Any idea what to do ?

How to drop 200 OK in onreply_route ?
by Denys Pozniak 09 Feb '21

09 Feb '21

Hello! In the configuration below Kamailio Proxy creates a transaction for the SIP PUBLISH to get info from the HTTP server in async mode. But before creating a transaction, a synthetic 200 OK is sent, so that I need somehow to drop the real 200 OK from the upstream Presence Server. If drop 200 OK in *reply_route*, tm module starts to retransmit. Those it is necessary that the 200 OK be consumed by the tm module, but does not go further. *if ( !is_method("PUBLISH") ) {* * sl_send_reply("200", "Ok"); t_newtran();* * $http_req(suspend) = 1; http_async_query("$var(url)", "CALLBACK");* *}* *route[CALLBACK] {* * <some header manipulation>* * t_on_reply("PUBLISH_REPLY"); route(RELAY); exit;* *}* *onreply_route[PUBLISH_REPLY] { if ( t_check_status("200") ) { drop; # Does not work!!! }}* Any advice is appreciated -- BR, Denys Pozniak

authenticated INVITE badly managed when topos is activated
by frédéric Gaisnon 08 Feb '21

08 Feb '21

Hi, If topos is activated and kamailio responds with a 407 "proxy authentication required" to an initial INVITE, INVITE received after with credentials (MD5 response in Proxy-Authorization header) is badly managed. Credentials are never validated and Kamailio responds 407 again. If topoh is used instead topos all works fine and credentials are validated. call flow is: Phone sends INVITE to kamailio SBC kamailio respond 407 "proxy authentication required" because SBC wants to authenticate caller Phone resends INVITE with Proxy-Authorization header with all valid information kamailio responds 407 again instead forwarding INVITE. My code: if (!pv_auth_check("$fd", "$sht(auth_cache=>$var(key))", "0", "1")) { auth_challenge("$fd", “1”); exit; } # user authenticated - remove auth header consume_credentials(); So if topos is used, pv_auth_check always returns false even if the phone sets valid information. If topoh is activated, pv_auth_check always returns true (same phone and same kamailio SBC versioning) I made my tests with kamailio 5.4.3 on centos 7. Regards, Frédéric Gaisnon

filter_body("application/sdp") on multipart/mixed; boundary with double Content-Length
by Karsten Horsmann 08 Feb '21

08 Feb '21

Hi List, I have some weird multipart/mixed;boundary issues. I use kamailio 5.3.6 with rtpengine 7.x.x (same with 8.x.x). If i try to remove a multipart/mixed and leave only the sdp with filter_body() that works except one thing. The sender used IMHO an non RFC compliant version of rfc5621 and wrote the Content-Length Header twice (one in the header, one in the sdp). After manipulating the SDP filter_body() lets Content-Length in the sdp (i guess). And rtpengine is not happy with the sdp after that. rtpengine [rtpengine.c:2588]: rtpp_function_call(): proxy replied with error: Failed to parse SDP Any ideas how to solve this? Kind regards Karsten Horsmann https://tools.ietf.org/html/rfc5621#section-3.1 route[REMOVE_MULTIPART] { if (has_body("multipart/mixed")) { if ($sel(cfg_get.remove.multipart) == 1) { if (filter_body("application/sdp")) { remove_hf("Content-Type"); append_hf("Content-Type: application/sdp\r\n"); msg_apply_changes(); xlog("L_WARN", "[$cfg(route)] Body part multipart/mixed with application/sdp found\n"); } else { xlog("L_ERROR", "[$cfg(route)] Body part multipart/mixed without application/sdp found\n"); } } else { xlog("L_INFO", "[$cfg(route)] Body part multipart/mixed found - manipulation disabled\n"); } } } ------------------- INVITE sip:+49XXXXXXXX@172.20.120.57:5060 SIP/2.0 Via: SIP/2.0/UDP 172.20.120.51:5061;branch=z9hG4bK-6589-1-0 From: sipp <sip:sipp@172.20.120.51:5061>;tag=6589SIPpTag001 To: sut <sip:+49XXXXXXXXX@172.20.120.57:5060> Call-ID: 1-6589(a)172.20.120.51 CSeq: 1 INVITE Contact: sip:sipp@172.20.120.51:5061 Max-Forwards: 70 Subject: Performance Test Content-Type: multipart/mixed;boundary=sonus-content-delim Content-Length: 1185 --sonus-content-delim Content-Type: application/sdp Content-Length: 305 v=0 o=Sonus_UAC 895311 862130 IN IP4 8.8.8.8 s=SIP Media Capabilities c=IN IP4 8.8.8.8 t=0 0 m=audio 26088 RTP/AVP 8 0 18 101 a=rtpmap:8 PCMA/8000 a=rtpmap:0 PCMU/8000 a=rtpmap:18 G729/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:18 annexb=no a=fmtp:101 0-15 a=sendrecv a=rtcp:26089 a=ptime:20 --sonus-content-delim Content-Type: application/pidf+xml <?xml version="1.0" encoding="UTF-8"?><presence xmlns="urn:ietf:params:xml:ns:pidf" xmlns:gp="urn:ietf:params:xml:ns:pidf:geopriv10" xmlns:cl="urn:ietf:params:xml:ns:pidf:geopriv10:civicLoc" mlns:btd="http://btd.orange-business.com" entity=" pres:geotarget@btip.orange-business.com"><tuple id="XXXX"><status><gp:geopriv><gp:location-info><cl:civicAddress><cl:country>DE</cl:countr <cl:A1>Some State</cl:A1><cl:A3>Somewhere</cl:A3><cl:A4>Somewhere</cl:A4><cl:A6>Somestreet</cl:A6><cl:YYY>1</cl:YYY><cl:PC>9999</cl:PC><cl:EMERGENCYZONE>XXXXXXX</cl:EMERG CYZONE></cl:civicAddress></gp:location-info><gp:usage-rules></gp:usage-rules></gp:geopriv></status></tuple></presence> --sonus-content-delim-- --------------------- INVITE sip:+49XXXXXXXX@foo SIP/2.0 Via: SIP/2.0/TCP 212.XX.XX.XX;branch=z9hG4bKc228.6b8fdf20d79998d1d355feb2dcf5ba63.0 From: sipp <sip:sipp@foo>;tag=6589SIPpTag001 To: sut <sip:+49XXXXXXXX@foo> Call-ID: 1-6589(a)172.20.120.51 CSeq: 1 INVITE Max-Forwards: 69 Content-Length: 347 Content-Type: application/sdp P-Asserted-Identity: <sip:+49XXXXXXXX@212.XX.XX.XX> Contact: <sip:btpsh-60211bbe-674b-1@212.XX.XX.XX;transport=tcp> Content-Length: 305 v=0 o=Sonus_UAC 895311 862130 IN IP4 8.8.8.8 s=SIP Media Capabilities c=IN IP4 8.8.8.8 t=0 0 m=audio 26088 RTP/AVP 8 0 18 101 a=rtpmap:8 PCMA/8000 a=rtpmap:0 PCMU/8000 a=rtpmap:18 G729/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:18 annexb=no a=fmtp:101 0-15 a=sendrecv a=rtcp:26089 a=ptime:20 -- Mit freundlichen Grüßen *Karsten Horsmann*

Retransmission of 407
by Marat Gareev 08 Feb '21

08 Feb '21

Hello, UAC sends INVITE to UAS, authorization procedure is required, therefore UAS responds with an 407 error code. At this point, the client does not respond with ACK, but the server does not send retransmits. Is this the expected behavior? * UAC -- SIPp, UAS -- Kamailio. Can the Kamailio be configured to send 407 code retransmissions? Thanks!
